」に換算し、そして換算して出た「円」の金額を更に「
ドル」に換算する事により、その価を算出するのがほと
んどである。
However, in order to calculate the amount based on the difference in exchange rates, first convert the amount in the country's currency to ``yen'', the flat Japanese currency, and then further convert the amount in ``yen'' to ``yen''.
In most cases, the value is calculated by converting it into dollars.

これがため換算に手間取るばかりか、応々にして計算違
いを犯したりして不愉快な思いをしている。
As a result, not only does it take a lot of time to convert, but I often end up making mistakes in my calculations, which is very unpleasant.

This system has the above-mentioned structure, so to explain its function according to the drawing, first of all, if the currency to be converted into "dollars" is, for example, British "pounds", then the annular rotating plate on side B 6 is rotated, and the standard scale "1", that is, "1 pound" indicated by the arrow on the calculation scale 7, indicates the position of the scale that indicates the amount when converted into Japanese currency, for example, "400 yen". Adjust it to the position of the calculation scale 8, and then rotate the rotating disk 2 on the A side in the same way until it reaches the reference "1" indicated by the arrow in the calculation scale 4, that is, "1".
The scale of "Dollars" is the amount converted to Japanese currency, for example "220
Align it with the position of the calculation scale 5 which indicates "Yen".

そこで、例えば「11ポンド」を「ドル」に換算した価
を知りたいとすれば、第2図に示す様に、指標枠9を回
動させてその指標線10を「11ポンド」を示す目盛位
置に合わせ、しかる後円板1を裏返す。
For example, if you want to know the value of "11 pounds" converted into "dollars," as shown in Figure 2, rotate the indicator frame 9 and set the indicator line 10 on the scale indicating "11 pounds." Adjust the position and then turn disk 1 over.

そして指標枠9の指標線10により示された、回転円板
2上の計算目盛4を読めば、「20ドル」となり、即ち
、「11ポンド」を「ドル」に換算すれば「20ドル」
となる事が直ちに分る事となるものである。
Then, if you read the calculation scale 4 on the rotating disk 2 indicated by the index line 10 of the index frame 9, it will be "20 dollars", that is, if you convert "11 pounds" into "dollars", it will be "20 dollars".
It is immediately clear that this is the case.

Therefore, according to the present invention, the structure is extremely simple, so it can be mass-produced at low cost, and there is no possibility of malfunction or damage.The method of use is as described above, simply by moving the indicator frame and reading the scale indicated by it. It is extremely easy because you can directly know the price converted to "dollars", and since the currency of the country is converted to "dollars" using "yen", it is possible to convert "yen" at the same time.
Since it is possible to recognize numbers converted into , it is extremely effective as a currency converter for overseas travelers and others to carry and use.
